Toall whom it may concern.-

Be it known that I, SILAs R. DIVINE, of North Tarrytown, county ofWestchester, 'State of New York, a citizen of the United States, haveinvented certain new and useful Improvements in Aerated Beverages, ofwhich the following is a full, clear, and exact description,

reference beinghad to the accompanying drawings, forming part of thisspecification, in which Figure 1 is aview in perspective, and Fig. 2 avertical section of the same.

My invention relates to aerated beverages; and it consists in aconcreted carbonated alkali and a concreted acid, as herein described,in individual masses in relative proportions, as hereinafter specified,inclosed in an envelope common to both, and with a partition thereinseparating the alkali from the acid, as and for the purposes hereinafterset forth.

In carrying out my invention I employ sodium carbonate or bicarbonate,or potassium bicarbonate or analogous carbonated alkalies, as a sourcefrom which to obtain carbonic acid to carbonate waters or beverages.

The acids I employ are preferably vegetable acids-such, for example, ascitric, tartaric, or malic --but some inorganic acids which areinnocuous to health may be used, such as phosphoric acid or acidphosphates; and in place of these acids the bisulphates of somealkalies, such as the bisulphate of potash or the bisulphate of soda,giving an acid reac tion, may be used, the excess of acid therefrombeing neutralized withthe carbonated alkalies and evolving carbonicacid.

I form a composition of matter by taking a carbonated alkali and,preferably,a neutral adhesive material-such as gum-arabic, sugar, orglucose-and mixing them together in the form of powders, then moisteningthe mixture with" water, .and then molding or pressing the plastic massinto determined forms, preferably into cylinders, and finally allowingthe forms to dry out and harden. I prefer to employ the neutral adhesivematerial to cause the particles of the carbonated alkali to cohere andform a concreted mass when hardened.

The adhesive material may, if desired, be moistened before beingincorporated with the carbonated alkali, instead of afterward. In

employing gum Ifind it desirable to use one part of gum to twenty partsof t-he'alkali, and in employing sugar or glucose I find it dosirable touse from ten to thirty parts of sugar or glucose to one hundred parts ofthe alkali. I find these proportions will efi'ectthe desired adhesion informing the described concreted masses. When beverages are to beproduced in which sugar is desired, I employ the sugar to cohere thealkali in the concreted masses, and in such cases theproportion of sugarmay be increased above that hereinbefore stated to such quantity as willgive the sweetness re-- qui red. When beverages are desired in whichthere is to be no sweetness, I prefer to employ the gum as the coherentmaterial.

I-employ this concreted composition of carbonated alkali and adhesivematerial in fabrieating aerated beverageaand I preferabl y em- 'ployitin connection with the powdered crystals of an acid, as hereinbeforespecified, con-- creted into a mass in an individual form or stick. Theacid may be concreted by moistening the powdered acid crystals withwater, and then molding the plastic mass into the desired form,preferably into a cylinder of the same diameter as the alkali-cylinders,and allowing the cylinder to crystallize or harden.

In carrying out my invention 1 take a stick or cylinder of the describedconcreted carbonated alkali and a stick or cylinder of the con cretedacid having the relative proportions hereinafter specified, and inclosesaid cylinders in an envelope common to both and with a partitiontherein separating the alkali from the acid cylinders.

In the drawings, A indicates the concreted cylinder of carbonated alkaliand gum or sugar, B the concreted cylinder of acid, 0 thedividing-partition, and D the common envelope. The dividing-partition ispreferably composed of stout parafiined paper, so as to be imperand'sothat the beverages on being decanted will retain a pleasant sparkle.

In using. my invention to produce an aerated beverage I remove the acidand alkali cylinders from the envelope and place them in a.

. I determined and proper vquantity of water, as

hereinafter specified, in a suitable vessel or bottle, which'is thenhermetically closed.

.I am aware that a carbonated alkali and an acid have been heretoforeput up in powders, in packages, in determined proportionsas, forexample, sedlitzpowders-and have been employed to generate gas in anopen orclosed vessel containing water; but the nature and scope of myinvention are essentially diflerent to such powdered substances. Thealkali and acid being in the form of powders, they dissolve almostinstantly in water,'and the carbonic acid is consequently evolved withgreat rapidity, and in the case of an open veuel passes quickly andtumultuously to the surface of the water and escapes, asmall percentageonly being absorbed by the water,while in case it is desired to closethe vessel the generation of gas is so rapid that its esmpe is eflected,together with a portion of the water, before the vessel can be closed.When my improved cylinders of concreted alkali and acid are employed,the cylinders will dissolve slowly in the water, and the evolution ofthe carbonic acid will be correspondingly gradual, the pressure in thevessel being gradually increased, and the gas, as it is slowly generatedand rises in fine bubbles, being readily absorbed by the water, so thatwhen the vessel is opened and the beverage is decanted it will possess acontinuing life and sparkle. The relative proportions in which theconcreted carbonated alkali and concreted acid ai-e employed are suchaswill liberate care bonic acid in a known volume to'oorrespond to thecapacity ofthe vessel in which the beverage is to be formed and thepmnre to be desired. To produce an aerated beverage with a pressure offrom four to five atmos- 4 5 pheres, which is desirable in fabricating apleasant and palatable drink,- I employ about sixty grains of sodiumbicarbonate as the alkali to about forty-five grains of citric acid tocarbonate about eight ounces of water and so give -an apparently neutralsolution. By increasing or decreasing the proportion of the acid asolution will be produced which will be distinctively acid or alkaline,respectively.

A desired flavor may be incorporated with 55 the concretedalkaline-cylinder, so as to produce a flavored beverage. -Well-knowncssential oils employed for flavoring maybe used. The oil may be mixedwith the gum or sugar,

or with the moistened plastic mass of the car- 5 bonated alkali and gumor sugar, previous to the drying or hardening of said cylinders. Theproportions in which the flavors are introdnced may be varied atpleasure.

I do not claim herein the process of making 5 aerated beverages byplacing a concreted carbonated alkali and a concreted acid, such asdescribed, in individual masses in a certain volume of water in a closedvessel and allowing the alkali and acid to dissolve, thus evolv- 7o ing,carbonic acid which is absorbed by.the' water, as the same is thesubject-matter of and is claimed in my application for Letters Patent,Serial No. 214,783, filed in the Patent Ollice September 28, 18 7 5 WhatI claim as my invention, and desire to secure by Letters Patent, is-' Asan article of manufacture, a concreted carbonated alkali and.a concretedvegetable acid, in individual masses and in the relative pr'o- 8cportions specified, inclosed in an envelope common to ,both masses, andwith a partition therein separating said masses, as and for the purposespecified.
